Claims.

This invention relates to the art of processing cartons, and the invention is concerned with the treating of paper cartons with parafiin.

An object of the invention is to provide improved means for subjecting the cartons to a bath of paraffin.

The invention together with its numerous objects and advantages will be best understood from a studyof the following description taken in connection with the accompanying drawings wherein:

Figure 12 is a detail sectional view taken substantially on the line I2-l2 of Figure 5.

Figure 13 is a detail view of a cam and roller assembly forming part of the ejector mechanism.

In accordance with my invention the cartons pass directly from the carton forming machine into a device for coating the cartons internally and externally with wax. Such wax-coating device in the present instance comprises a suitable casing 6, the walls of which are suitably insulated. Access to the casing 5 is had at one side thereof through the medium of oppositely shiftable sliding doors 6-6 equipped with handles I. At the meeting edges thereof the doors 66 are suitably notched to provide therebetween an opening 8 through which the wax-coated cartons exit from the casing 5.

At the opposite side thereof the casing 5 is provided withan entrance opening 9 and through which the cartons pass into the casing 5 from a conveyor l0. Conveyor Ill, in actual practice will have its intake end suitably 601....16Cli6d'Wil'1h or aligned with the discharge conveyor leading from the aforementioned carton-forming machine (not shown).

Suitably and rotatably mounted within the casing 5 adjacent one side thereof is a dipping wheel indicated generally by nLu'neral H.

The wheel It may be of any suitable construc tion and is provided on its periphery with a, circular series of skeleton frame-like radial pockets l2 of a size and shape to accommodate the cartons. In this connection it will be understood that the respective pockets l2 are opened at opposite sides thereof so as to permit a carton to pass into the pocket from one side of the wheel and to discharge from the pocket at the opposite side of the wneel. Also the *ructure of the pocket is such as to insure a thorough immersion of the carton therein in the bath of liquid paraflin 13.

In order to prevent the cartons from slipping laterally out 01 the pockets l2 there are provided in the casing, and at one side of the wheel, substantially split circular, concentric retaining rods l4 mounted or supported by pairs of vertical.

wheel ii and for ejecting 9. treated carton from a pocket l2 simultaneously with the positioning of an untreated carton within a, pocket I2. The mechanism whereby the foregoing is accomplished will now be described.

Located adjacent to one side of the casing 5 is a platform or stand IS on which is mounted a suitable frame structure including a guide frame I'I. Frame II has opposite sides thereof\ provided with slots I8 in which operate rollers I9 provided on the end of a shaft 20 (see Figure 12). Shaft 20 has pivoted thereto a yoke 2| provided on one end of an ejector rod 22. Rod 22 is provided for the purpose of ejecting a coated carton from a pocket I2, the ejected carton passing from its pocket I2 onto a trackway 23.

The cross rod or shaft 20 is caused to reciprocate within the guide II through the medium of a link 24 that at its upper end is pivoted to a yoke 25 carried by the cross shaft 20. At the lower end thereof the link 24 is pivoted as at 26 to a base 21 provided on the platform I6. Adjacent said lower end the link 24 is provided with a lateral roller 28 is is normally urged through the medium of a suitably provided coil spring 29 into engagement with a cam groove provided on a cam 30. Cam 34 is mounted on a driven shaft 3| suitably supported by bearing brackets 32 rising from the aforementioned base 21. Thus it will be seen that as shaft 3| rotates link 24 is caused to oscillate thus in turn causing the shaft 2|] to reciprocate back and forth carrying with it the ejector arm 22. Obviously, as the arm 22 moves forwardly it passes through the open ing 9 into the casing 5 to contact a carton in a I pocket I2 as the said pocket passes into position opposite the opening 9. Contact of the arm 22 with said carton will cause the latter to be forced transversely with respect to the wheel II out of said pocket and onto the aforementioned track 23.

For transferring the cartons from the conveyor I0, and forcing the cartons successively into succeeding pockets I2 as the wheel II rotates there is provided an ejector arm 33. The arm 33 works in suitable guides 34 and is normally urged to a feeding position through the medium of a coil spring 35 anchored at one end to a guide 34 and at a relatively opposite end connected with the arm 33 through the medium of a. hook-like rod extension 36. At the operating end thereof the rod 33 is provided with a head 31 to which is secured in any suitable manner one flange 38 of a substantially L-shaped plate the other flange or arm 39 of which is adapted to move with the arm 33 transversely across the conveyor I to act as a stop for the succeeding cartons 44 as the foremost carton is being passed from the conveyor I0 into a pocket I2.

The arm 33 is releasably retained in a retracted position through the medium of a latch dog 4I pivotally mounted in proximity to the arm 33 and having one end engaging akeeper block 42 carried by the arm 33 as shown in Fig-' ure 10. Said end of the dog 4| is normally urged into engagement with the keeper block 42 through the medium of a suitably provided coil spring 43.

The latch 4| is operated from a trip 44 and to that end there is suitably provided a vertical shaft 45 provided adjacent its lower end with an arm 46 connected to the latch 4| through the medium of a link 41. Adjacent the upper end thereof the shaft 45 is provided with an arm 48 to which is pivoted one end of the trip 44. Arm 48 has extending angularly therefrom a lug 49 between which and an end portion of the trip 44 a coil spring -50 is disposed.

At the end of the conveyor I0 terminating opposite the opening 9 there is disposed across the conveyor a perpendicular wall or plate member 5|. Plate 5| is provided with a slot 52 through which the offset free end of the trip 44 normally extends to be engaged by the foremost carton 4|! as the latter moves with the conveyor I0 to the discharge end of the conveyor.

From the above it will be seen that as the foremost carton 40 moves into contact with the trip 44 the latter will be caused to move inwardly through the slot 52 against the action of spring 50 resulting in a rocking of the shaft 45. Movement of the shaft 45 is transmittedthrough the link 41 to the latch 4| thus causing the latch 4| against the action of spring 43 to swing out of engagement with the keeper block 42. Upon disengagement of the latch 4| in this manner feed arm 33 will, under the action of spring 35, be caused to move in a direction to engage the flange 38 of the L-shaped head with the aforementioned foremost carton 4U forcing the latter through the opening 9 andinto a pocket I2 of the wheel II.

Carried by the arm 33 is a lateral lug 53 arranged in the path of a lug or projection 54 arranged on one end of the shaft 20. Thus it will be seen that with latch 4| in a released position lugs 53 and 54 will cooperate for transmitting return movement of the shaft 20 to the arm 33 for retracting the latter against the action of spring 35..

In connection with the above it will be understood that when the device is in operation arms 22 and 33 will be reciprocating rapidly so that during the operation of the device practically at no time are lugs 53 and 54 out of contact one with the other. Consequently as one pocket I2 is receiving a carton to be treated the next succeeding pocket is having a carton ejected therefrom.

The shaft on which the wheel II is mounted is indicated by the reference numeral 55'and has an end portion thereof supported by the bearings 32 as shown in Figure 5. On the shaft 55 there is provided a gear 56 that is in constant mesh with a gear 51 provided on one end of a jack shaft 58 (see Figure 3).

For driving the shaft 58 intermittently, or substantially step-by-step from the driven shaft 3|, there is provided on the shafts 3| and 58 complemental elements forming a Geneva movement, said complemental elements including the wheel 59 carried by the shaft 3| and a slotted wheel 60 carried by the shaft 58. Wheel 59 has between the flanges thereof the usual tooth pin 6| that engages successively the slots provided in the usual manner in the wheel 60 as clearly shown in Figure 6. Thuscit will be seen that the Wheel II is caused to revolve in a step-by-step manner so that the wheel will be at rest during the actual positioning of a carton within a pocket I2 and the ejecting of a treated carton from a second pocket I2.

To insure. that the wheel II will be positively steady for each period of rest, and thereby assure a smooth operation of the device, there is also provided on the shaft 55 a notched wheel 62. The notches in the periphery of the wheel 62 correspond in number to the number of pockets I2 on the wheel II and cooperable with the notches in the wheel 62 is a spring biased dog 63.

As shown in Figure 4 dog 63 is pivotally mounted on a suitable post 64 provided therefor and has the bill 65 normally urged upwardly to err-- gage a notch in the periphery of the wheel 92 through the medium of a suitably provided spring 68.

Adjacent the bill end thereof dog 83 is equipped with a roller 61 that is engageable with the periphery of a cam 68 on the shaft 3|. Thus it will be seen that cam 68 cooperates with the roller 81 for moving the bill'65 of the dog 83 out of engagement with a notch in the wheel 52 at the point of operation necessary to release the shaft 55 for revolvingthe wheel II the necessary fraction of a revolution for bringing the proper PO ket into alignment with the respective ejector arm 22 and feed arm 33.

The driven shaft,3l is driven from an electric motor 59 mounted on the stand I6 and in driving engagement with the shaft 3| through the medium of gearing suitably provided in a gear box I9, and intermeshing gears II, 12. v

The casing 5 is filled to a proper level with wax and to maintain a constant level of the wax within the casing 5 there is provided on the discharge end of the feed pipe I3 a valve 14 equipped with a float 15. Valve '14 as shown in Figure 7 connects the pipe 13 with a discharge pipe, 15

that extends downwardly to terminate at its dis-= charge end at a point above the bottom of the casing 5.

For maintaining a supply of wax, in liquid form, to the casing 5 there is suitably provided a reservoir H (see Figure 1), in which the block of wax or parafiin is placed. Leading from the bottom of the reservoir 11 is the aforementioned feed pipe I3. The reservoir I1 is provided with a vertical transverse partition 18 in the form of a strainer and the block of wax or paraffin is placed in the reservoir at one side of the strainer, the liquid wax passing through the strainer I8 to flow from the reservoir 11 through the conduit 13 to the casing 5.

For melting the wax within the reservoir 11 there is provided a steam coil 19. Also to maintain the wax in a fluid or liquid state as it passes through the conduit I3 coil 19 has leading therefrom and extending through the conduit I3 a pipe 89.

Also provision is made for making use of the warm air above the paraffin level I3 in the caslng 5 for freeing a treated carton of excessive wax or paraffin as the carton is being ejected from a pocket I2.

Such means as above referred to comprises a blower casing 8I suitably mounted on the top of the casing 5 and having an inlet conduit 82 that extends into an opening in the top of said casing. The top of said casing adjacent to said opening is provided with a pair of opposed oppositely facingbrackets 83 as shown in Figure 9, and engageable with these brackets 83 are lugs 84 provided on opposite sides of, an inlet pipe extension 85 that is positioned within the casing 5. Obviously to engage the lugs 84 with the brackets 83, pipe section 85 is rotated in one direction, and to disengage the lugs 84 from the brackets 83 pipe section 85 is rotated in a reverse direction. Thus provision is made whereby the pipe 85 may be used or not as found desirable and when used can be quickly secured in alignment with the blower intake 82. When used pipe 85 terminates at its lower end slightly above the level of-the parafiin bath as shown in Figure 7.

It will thus be seen that when the device is in operation warm air from above the level of the forced by the blower downwardly through the outlet 88 of the blower onto the carton resting on the track 23, This warm air will serve to remove excess paraflln from the carton.

In connection with the above it will be seen that the outlet 86 of the blower extends downwardly through the top of the casing 5 and at its lower end merges into a suitably shaped shield 81 provided to prevent a too great diffusion of the warm air and thereby insuring the obtaining of the full benefits of the warm air blast in the removing of this excess paraffin.

For maintaining the parafiin within the casing 5 in suitable liquid state there is suitably provided within the casing 5 the steam coils 88, coils 88 and I9 being connected in any suitable manner with any suitable source of steam supply.

To insure the retaining of the cartons in a vertical position on the track 23 there is suitably mounted above the receiving end of the track, as shown in Figure 5, a carton-contact strip 89 having a suitably offset portion adapted to yieldably bear against the uppermost end of the carton. Also to maintain a suitable restraint on the carton as it approaches the incline 23a of the track 23 there is suitably mounted so as to extend into the upper portion of the opening 8 a relatively shorter carton-contact member 99 that has an offset end adapted to be adjusted downwardly as conditions may require through the medium of a suitably provided adjusting screw 9|.

A suitable frame structure indicated generally by the reference numeral 92 is provided for supportng the aforementioned feed conveyor I9 and also for supporting a conveyor 93 disposed above and parallel to the conveyor I9. Conveyor belt 93 engages the uppermost ends of the cartons 49 on the conveyor I9 and serves to maintain the cartons perpendicularly on the conveyor I9 and to insure a proper "crowding of the cartons as they feed from the carton-forming machine to the paraflining device of my invention.

Also there are provided in connection with the conveyor I9 21. pair of parallel side rails 94 between which the cartons 49 pass and these rails serve to prevent the cartons from working laterally in either direction out of line.

The conveyor I9 is adapted to be driven in any suitable manner from the outlet conveyor (not shown) of the carton-forming machine, also not shown. Drive from the conveyor I9 is transmitted to the conveyor belt 93 through the medium of suitable chain and sprocket mechanism indicated generally by the reference numeral 95.

The extension 23a of track 23 extends outwardly of the casing 5 between a pair of opposed side walls 96, 91 which at their outer ends merge into a front wall 98 paralleling a wall 99 that forms with the wall 98 a receiving chamber for the cartons 49 as they pass from the track extension 23a.

In connection with the above it will be noted that the wall 99 curves rearwardly and in the direction of the-track extension 23a at its upper edge, merging into an inclined abutment I99 that extends upwardly from the lower end of. the

track extension 23a. It will thus be seen that as the cartons 49 move downwardly on the track extension 23a they come into abrupt contact with the abutment I99 with the result, as clearly shown in Figure 5, the cartons are caused to upset'and in an inverted position pass downwardly between the walls 98 and 99 so that in an upright position they are received on an endless conveyor I9I.

Disposed beneath the receiving end of the conveyor IOI is a pan I02 which at the side thereof nearest to the casing 5 is extended upwardly a considerable distance as at I03. The wall I03 at its upper edge is provided with a flange extension I04 that at its edge is suitably secured to the adjacent side of the casing 5 below the opening 8 and forms a drip-shield for returning the paraffin drippings from the cartons 40 back to the casing 5 through an opening I05 provided in said wall of the casing 5 as clearly shown in Figure 5.

The pan I02 serves to receive the drippings from the upright cartons 40 as they come to rest on the conveyor IOI.

Also accommodated within the pan I02 is a removable drip pan I06, the same being supported by suspension brackets I'I that depend from the side bars I08 forming part of the conveyor assembly IOI.

Further in accordance with the present invention and as best shown in Figure 5, walls 98, 99 are provided with passages I09 and the track 23a is hollow so as to provide for a circulation of steam to the end that the paraflin on the cartons will not completely congeal at this stage of operation of the device.

Also in order to maintain the drippings within the pan I06 in a suitable fluid state a steam coil IIO extends into the pan I02 beneath the pan I06 and has suitable connections with the passages I09 in wall 98.

The conveyor assembly ,IOI embodies a series of parallel endless spring conveyor bands trained over suitable sheaves, and the upper ones of these bands are supported at intervals by cross bars II2.

Beneath the conveyor in proximity to the easing there is disposed a pan II3 through which extends vertically one end of a pipe II4 that at its upper end is equipped with an elongated shelllike spray nozzle II5 provided for directing a spray of water upwardly and against the cartons for cooling the wax coatings of the ca: tons.

Obviously pan I I3 will serve to catch the water admitted from the nozzle I5 and to provide for a continuous circulation of the water pipe H4 is connected to a pump H6 at the outlet end of the pump while a drain pipe III extending from the bottom of the pan I I3 connects with the inlet side of the pump I I6.

Also suitably arranged within the pan H3 is a refrigerating coil H8 that will serve to maintain the water at a very low temperature.

Immediately from this application of water thereto the cartons pass over nozzles I I9 provided for subjecting the cartons to a cold air treatment,

nozzles II9 being connected with a source of cold air supply.

For'maintaining the cartons upright on the -"c0n? or Iill there are provided in any suitable manner above the conveyor, and at opposite sides .crank I3I.

it passes through said opening, and in a manner clearly shown in Figure 1.

Means is also provided to prevent detrimental jamming of the machine in the event, for some reason or other, the cartons 40 should not properly pass from the track extension 23a onto the conveyor assembly IOI. To that end there is provided adjacent the wall 96 a bracket structure I23 in which is journaled a vertical shaft I24. On the upper end thereof shaft I24 is provided with an arm I25 that is normally disposed in a position above the point of merger of the track extension 23a with the wall abutment extension I00, While on the lower end of the shaft I24 is a longer arm I26 that is disposed adjacent the forward end of the wall 96. The shaft I24 also has an arm I2I extending therefrom. Also mounted in proximity to the wall 96 is a switch box I28. A spring I29 is anchored at one end to the box I28 and is connected at its other end to the arm I21 and serves to normally urge the shaft I24 to rotate in a clockwise direction for positioning the arms I25 and I26 so that under circumstances hereinafter more fully explained one or .the other of the arms will go into operation.

The arm I2I is connected through the medium of a suitable link I30 with one end of a bell Bell crank I3I is pivotally mounted as at I32 on one end of the aforementioned switch box I28 and has a free arm extending into the box I28 to engage a mercury switch I33 suitably and pivotally mounted Within the box I28 as shown in Figure 8.

From the above it will be seen that in the event a jamming of thecartons should occur either at the lower end of the track extension 23a or at the point where the cartons pass downwardly between the walls 98, 99 either the arm I25 in the first instance, or arm I26 in the second instance, would be contacted by the carton in such a manner as to cause the shaft I24 to swing against the action of spring I29. This would result in a swinging of the bell crank I3I in a direction to swing the switch I33 to a position interrupting the circuit to the motor 69, it being understood that switch I33 is suitably connected in circuit with the motor 69. Thus upon the interrupting of the circuit to the motor 69 in this manner the conveyors and the wheel II will be brought to a standstill thus preventing damage either to the machine or to the cartons.

When the cartons are again properly arranged, and the jam broken, switch I33 will be again tripped for completing th circuit to the motor 69 so that the device will again go into operation.

This application is a substitute for a corresponding application filed by me under date of March 11, 1938, and identified as Serial No. 195,- 387, the same having been allowed May 22, 1940. and now abandoned.
